Calculate the answer and Jacobian of a non-scalar-to-non-scalar function, automatically choosing between forward- and reverse- mode AD based on the relative, number of inputs and outputs. If you need to support functions where the output is only a Functor, consider using jacobianT from Numeric.AD.Forward or jacobian2 from Numeric.AD.Reverse directly.

Exposed Types

AD serves as a common wrapper for different Mode instances, exposing a traditional
numerical tower. Universal quantification is used to limit the actions in user code to
machinery that will return the same answers under all AD modes, allowing us to use modes
interchangeably as both the type level "brand" and dictionary, providing a common API.
